Review on Corsair ML120 Pro LED Red Cooling Fan: Premium 120mm Magnetic Levitation for Optimal Cooling - CO-9050042-WW by David Butterfield

Bought 5 of these to redo the cooling in my case/heatsink. The mounting holes are exactly 120mm, but since the actual fan housing is 1-2mm larger than a "normal" 120mm fan, they are not suitable for places that require a normal size (e.g. heatsinks or smaller ones Housing). Not sure why Corsair did this as the extra size serves no purpose and limits application. In any case, it should be noted in the description.
